Troubleshooting
Reason:
Correction:
10� In line relief valve set too low�
In line relief valve pressure should be 3100 PSI (214 bar)�
Set spinner control valve to “0”� Disconnect pressure line,
coming from rear port on spinner control valve, at control�
Reconnect this line to flow meter inlet port. Disconnect
return line from control where it joins the return tube
running to the reservoir. Connect flow meter load valve
to return tube� Open load valve fully, run truck engine at
max RPM� Slowly close load valve until pressure reaches
3100 PSI (214 bar)� If this pressure cannot be reached,
set up relief valve adjustment until gauge reads 3100 PSI
(214 bar)�
CAUTION: Do not set pressure above 3100 PSI (214 bar)�
11� Jammed or frozen conveyor hydraulic
motor�
Replace motor�
12� Conveyor hydraulic motor shaft key
sheared�
Replace key�
13� Pump speed is not adequate to provide
sufficient flow to maintain spinner speed.
Increase engine speed or resize hydraulic pump to meet
system requirements�
14�
Insufficient hydraulic oil flow at normal
driving speeds�
Check PTO-Pump matching. If insufficient flow results,
install higher percent PTO or use larger pump (Special)�
15� Defective spinner control valve�
Replace valve metering spool spring� If no improvement,
replace spinner control valve�
16� Cab control is for conveyor only—
spinners run anytime vehicle engine is
running, PTO is engaged and spinner
control valve is in a running position�
None required� This is a normal condition� To stop
spinners, set spinner control valve at “O” position,
disconnect PTO, or shut off vehicle engine�
17� Excessive oil is being pumped�
1� PTO percentage too high� Change PTO to smaller
percentage or use smaller pump�
2� Pump is too large� Do not exceed 40 GPM (151
LPM) pumping rate� Change to smaller pump or use
smaller percentage PTO�
3�
Pressure drop in control valve is sufficient to run
lightly loaded conveyor motor� Shut off pump drive
by disengaging PTO shaft�
16� Worn motor (spinner or conveyor)�
Motor heats up at an excessive rate (check for this heating
when system is cold)� Replace motor�
17� Improper or deteriorated hydraulic oil�
Replace hydraulic oil with proper specification oil and
replace filter.
18� Pinched or obstructed hose, hydraulic
line or fitting.
Clear obstruction or replace part� Straighten kinked
hoses�
19� Driving too fast for application rate�
Shift truck transmission to a lower gear� Will not normally
occur if within maximum application rates�
20� Involves the controller�
Refer to control manual�
